The larger dishes should be a big help for him Sue. I bet if you steam some carrots and broccoli so it's soft that he would like that also. Probably chunks of baked sweet potato would work well too.
We have a lot of good recipes in our Recipe Forum that would be good for him. Things he could pick up to put in his mouth.
I looked up a few, but check out the forum, lots of yummy stuff in there;
Sweet Potato Burrito
1 Sweet Potato
Unsweetened Fruit Juice
Sprinkle of Cinnamon
¼ cup chopped Almonds or Walnuts
Whole Grain Bread
Steam your Sweet Potato until tender, peel and mash. Add chopped nuts and Cinnamon. Add a small amount of unsweetened fruit juice to the mashed Sweet Potato/Nut mixture to make a paste.
Flatten a piece of Whole Grain bread with a rolling pin. Spread a layer of the Sweet Potato mixture on the bread and roll tightly like a burrito. Slice and serve!
You could probably even add some finely chopped greens to the sweet potato mixture.
Here's a link to the 5 Grain Cookie Recipe which would be good for him to put pieces in his mouth;

The soft foods should help a lot to get a better diet into him, while the vet is working on his beak.
